# Chat with services

LLMS index: [llms.txt](/llms.txt)

Use Go Micro’s agent to call your services from a terminal conversation.
You do not need the gateway or an external MCP client.

## Before you start

Install the CLI:

```sh
go install go-micro.dev/v6/cmd/micro@v6.15.1
export PATH="$(go env GOPATH)/bin:$PATH"
```

Keep your service running. If you need one, use the
[service quickstart](../quickstart.md). Check discovery before starting chat:

```sh
micro call notes Notes.List '{}'
```

The CLI and service must use the same registry. See
[service discovery](../services.md#discovery) if multicast is unavailable.

## Start chat

```sh
micro chat
```

With no registered agent, this starts a local development agent. On first use,
choose a provider, enter its key, and select a model. Requests use that provider
account. Ask **“What notes do I have?”** and check the service call in the tool
activity. The quickstart service returns “Review the release” and
“Update the documentation”.

If an agent is already registered, `micro chat` connects to it instead;
the running agent owns its model configuration. You do not need to start a
second agent or enter its credentials in the client.

To choose instructions, model, and service access in your own code,
[define an agent in Go](../agents.md).
